Other claims from this paper (11)
- Observation Garlic essential oil showed four major gas-chromatographic peaks.
- Observation The garlic peaks were identified as diallyl mono-, di-, tri- and tetra-sulfides.
- Observation The highest garlic essential oil peak was diallyl disulfide.
- Observation Garlic oil contained only trace amounts of dimethyl mono- and di-sulfides.
- Intervention effect Diallyl trisulfide treatment gave a budbreak rate that was not uniform.
- Intervention effect Diallyl trisulfide treatment accelerated the first budbreak of grapevine cuttings.
- Intervention effect Exposure to volatiles of diallyl di- and tri-sulfides was the most effective treatment for promoting budbreak, irrespective of concentration and duration.
- Intervention effect Volatiles of 30% dimethyl disulfide suspension markedly inhibited budbreak.
- Intervention effect Authentic dimethyl disulfide and its 10% suspension promoted budbreak.
- Intervention effect Dimethyl sulfide and diallyl sulfide effects on budbreak varied with concentration and duration of exposure.
- Mechanism Sulfur-containing compounds with an allyl group, particularly diallyl disulfide, are the active substances that break bud dormancy in grapevines.
